Hello I have been looking at a 2003 f-350 and it also has a 6.0L in it. I was wondering what all the common problems with them and do the 4x4 have any front end problems? Thanks
Welcome to FTE fordman49 If you read through the Tech Folder and some of the threads most of the problems with the engine is EGR related and head bolts stretching. 2003 was the first year production for the 6.0L to meet EPA restrictions. I have an 03 and love it, EGR is deleted along with head studs installed. If you use the truck with factory programming, cleaning the EGR and turbo are common requirements to keep the engine in top condition.
Front end wear is normal, when inspecting a used truck that displays high miles, pay close attention to upper - lower ball joints, end play in tie rods and wear to suspension bushings. The Dealer may be able to provide you with a brief history through an Oasis report although the Dealer is not obligated to do so
I have a early built 03, which has been lift since 05. Only did ball joints and thats it on my truck minus the things I blew up on my truck cause of what I have done to it hehehehe. Other then that just like said above do the oasis report and see the history of the vehicle is good or bad.
So whats the deal with the stretching bolts? why do the head bolts stretch? Does the engine get hot? I am a mechanic here in my home town and I have done some light diesel work but mostly gasoline engines. Stuff like this is good to know please explain? Thanks
Then head bolts on a stock 6.0 are weak to begin with, when you start adding more boost, and timing raising compression the studs then to stretch over time, causing the head gaskets to fail, also the heads can become warpped as well.
When they do stretch what happens is that where ever the gasket fails coolant ends up into your cylinders which can cause the white smoke and smell coming from the exhaust. Also with the head gaskets fail when pressure is built up and it send it backwards through the cooling system which sometimes show signs in the degas bottle puking. Best way to find this out is hooking a meter and seeing if your getting those gases in the degas bottle.
Doing an EGR delete kit with help eliminate the problem, with an EGR system still active in the truck the exhaust is used to heat the coolant up when it passes through the egr now then raises coolant temps. With you deleting it, you eliminate that aspect in the equation so the coolant isnt heated by the exhaust anymore and will save you time from it blowing up and causing other issues to your truck which could be oil in the coolant and vise versa. This will keep the egr from failing in the future. That should cover most of it.

The OEM bolts (not studs) are Torque-to-Yeild (TTY) The ARP studs allot of folks are running aren't TTY and are slightly larger than the bolts. Over boosting (tuner induced) and high coolant temps (plugged EGR/oil cooler) are two of the common reasons the bolts stretch causing the heads to lift.

Maybe I'm looking at it the wrong way, but I thought the purpose of the EGR cooler was to cool the exhaust gases coming into intake. If it was to heat the coolant up, then all the guys running EGR deletes (kits & homemade) would have all kinds of issues then. True, once you take the exhaust out of the EGR equation...your not heating the coolant up anymore than the block it's self is doing.
On a related note...and it can't be stressed enough; routine/preventative maintence is a must for the 6.0L. Use the right filters...not "will fit" and do it on time. Skip out on it and you'll suffer the wrath of the "Combine Demon"...almost as bad as the scorn of a woman.
If I was to get this truck is the EGR delete kit something that I should? Is it something that will make the truck breath better? What I mean is it something that I would need to do right a way? The truck is a 03 King ranch F-350 it has 119k on it and I know both guys that owned the truck so it ben well taken care of. Deal is that the guy has to many trucks and he cant drive them all. Dude told me that he would sell it to me for 10 grand so thats why I am asking question.

Thanks for all the info

These motors/trucks can and will live a long time provided you do the routine maintenance. I've said it before, Bill Hewitt's YouTube channel has some interesting information for PSD owners. If you ever wondered how far a 6.0 will go:
I have a 03 F-450 and I have had to do the turbo from coking up since then its been good. I had Ford install a reman turbo it was the only way to go.
Keep in mind the trucks before the ultra low sulphur fuel had carbon problems so you have to clean up the carbon problems then from now on it shouldn't be such a problem. The fuel doesn't burn as dirty as past diesel fuel.
Make sure the truck has all the updates and flashes done.
mine is an early 03 6.0 and it has 129000 miles and I'm very happy sofar (nock wood). Very strick with maintance, and always use ford filters. Good luck.
Hey guys is There any upgrades that i can do to it for more power with out causeing any problems? I'd like get some power out of it but don't want to have any problems with headbolts. I was thinking about mabe a high flow exhast or a better air cooler. I think I am convenced about getting this truck. Do y'all have any advice on that?
I would not worry about more power, the truck has enought to do what it was made for. I would take no ones word on what was serviced and when. Expect to change everything, coolant, oil, fuel filters, rear gear oil, transfer case oil, transmission flush and new external filter for your piece of mind. This should set you back several hundred, and it's throwing good money at the truck.

I'll argee with "ljutic ss"...do you really need more power out of an engine that's putting 325Hp across the flywheel? Granted you can increase your fuel mileage when you bump the horsepower up. The three things at the top of my list for a longer life for my F250 (A) coolant filter (B) 4" turbo back exhaust & no cat and [like the looks of MBRP] (C) SCT tuner for an economy tune. Bismic has a list of things that for anyone serous about keeping their trucks for a long time (ten plus years).
